This is my first Post.
Hopefully someone will have time to answer a few questions newbie.
I'm in the process of transitioning from OS Windows to Kali Linux.
To Launch Kali, I am running Kali Alive from a USB Flash drive.

Initially my problems are Getting volume turned on, Task Manager, Saving Changes.

(Q) Can someone tell me how can I get the volume control button visible. Right now everything is muted.
I went to All settings, Sound. But everything is Read protected only.There some Youtube related to this question, but I can't
get any sound.

(Q) In OS Windows, there is an option to monitor/delete active applications, files etc. What is the Linux version of Task manager.

(Q) As mention before, I launch a fresh copy of Kali Alive to get in. Obviously any documents, bookmarks etc created, disappear when
a new copy of Kali alive is launched. How do you maintain docs, bookmarks in Kali. Right now I transfer Docs to OS windows to save, but I want to get off
Windows eventually
.
(Q) There are a number of programs on Kali Alive, can you suggest what a beginner should learn first.
I don't want to bother you people all the time. Are there any on-line books on Kali for beginners you can recommend.

Thanks for your help
Jef.
